-world-wide, royalty-free, non-exclusive license, to the extent of
-Apple's Applicable Patent Rights and copyrights covering the Original
-Code, to do the following:
-
-2.1 Unmodified Code. You may use, reproduce, display, perform,
-internally distribute within Your organization, and Externally Deploy
-verbatim, unmodified copies of the Original Code, for commercial or
-non-commercial purposes, provided that in each instance:
-
-(a) You must retain and reproduce in all copies of Original Code the
-copyright and other proprietary notices and disclaimers of Apple as
-they appear in the Original Code, and keep intact all notices in the
-Original Code that refer to this License; and
-
-(b) You must include a copy of this License with every copy of Source
-Code of Covered Code and documentation You distribute or Externally
-Deploy, and You may not offer or impose any terms on such Source Code
-that alter or restrict this License or the recipients' rights
-hereunder, except as permitted under Section 6.
-
-2.2 Modified Code. You may modify Covered Code and use, reproduce,
-display, perform, internally distribute within Your organization, and
-Externally Deploy Your Modifications and Covered Code, for commercial

-(a) You must satisfy all the conditions of Section 2.1 with respect to
-the Source Code of the Covered Code;
-
-(b) You must duplicate, to the extent it does not already exist, the
-notice in Exhibit A in each file of the Source Code of all Your
-Modifications, and cause the modified files to carry prominent notices
-stating that You changed the files and the date of any change; and
-
-(c) If You Externally Deploy Your Modifications, You must make
-Source Code of all Your Externally Deployed Modifications either

-longer. You should preferably distribute the Source Code of Your
-Externally Deployed Modifications electronically (e.g. download from a
-web site).
-
-2.3 Distribution of Executable Versions. In addition, if You
-Externally Deploy Covered Code (Original Code and/or Modifications) in
-object code, executable form only, You must include a prominent
-notice, in the code itself as well as in related documentation,
-stating that Source Code of the Covered Code is available under the
-terms of this License with information on how and where to obtain such
-Source Code.
-
-2.4 Third Party Rights. You expressly acknowledge and agree that
-although Apple and each Contributor grants the licenses to their
-respective portions of the Covered Code set forth herein, no
-assurances are provided by Apple or any Contributor that the Covered
-Code does not infringe the patent or other intellectual property
-rights of any other entity. Apple and each Contributor disclaim any
-liability to You for claims brought by any other entity based on
-infringement of intellectual property rights or otherwise. As a
-condition to exercising the rights and licenses granted hereunder, You
-hereby assume sole responsibility to secure any other intellectual
-property rights needed, if any. For example, if a third party patent
-license is required to allow You to distribute the Covered Code, it is
-Your responsibility to acquire that license before distributing the
-Covered Code.
-
-3. Your Grants. In consideration of, and as a condition to, the
-licenses granted to You under this License, You hereby grant to any
-person or entity receiving or distributing Covered Code under this
-License a non-exclusive, royalty-free, perpetual, irrevocable license,
-under Your Applicable Patent Rights and other intellectual property
-rights (other than patent) owned or controlled by You, to use,
-reproduce, display, perform, modify, sublicense, distribute and
-Externally Deploy Your Modifications of the same scope and extent as
-Apple's licenses under Sections 2.1 and 2.2 above.
-
-4. Larger Works. You may create a Larger Work by combining Covered
-Code with other code not governed by the terms of this License and
-distribute the Larger Work as a single product. In each such instance,
-You must make sure the requirements of this License are fulfilled for
-the Covered Code or any portion thereof.
-
-5. Limitations on Patent License. Except as expressly stated in
-Section 2, no other patent rights, express or implied, are granted by
-Apple herein. Modifications and/or Larger Works may require additional
-patent licenses from Apple which Apple may grant in its sole
-discretion.
-
-6. Additional Terms. You may choose to offer, and to charge a fee for,
-warranty, support, indemnity or liability obligations and/or other
-rights consistent with the scope of the license granted herein
-("Additional Terms") to one or more recipients of Covered Code.
-However, You may do so only on Your own behalf and as Your sole
-responsibility, and not on behalf of Apple or any Contributor. You
-must obtain the recipient's agreement that any such Additional Terms
-are offered by You alone, and You hereby agree to indemnify, defend
-and hold Apple and every Contributor harmless for any liability
-incurred by or claims asserted against Apple or such Contributor by
-reason of any such Additional Terms.
-
-7. Versions of the License. Apple may publish revised and/or new
-versions of this License from time to time. Each version will be given
-a distinguishing version number. Once Original Code has been published
-under a particular version of this License, You may continue to use it
-under the terms of that version. You may also choose to use such
-Original Code under the terms of any subsequent version of this
-License published by Apple. No one other than Apple has the right to
-modify the terms applicable to Covered Code created under this
-License.
-
-8. NO WARRANTY OR SUPPORT. The Covered Code may contain in whole or in
-part pre-release, untested, or not fully tested works. The Covered
-Code may contain errors that could cause failures or loss of data, and
-may be incomplete or contain inaccuracies. You expressly acknowledge
-and agree that use of the Covered Code, or any portion thereof, is at
-Your sole and entire risk. THE COVERED CODE IS PROVIDED "AS IS" AND
-WITHOUT WARRANTY, UPGRADES OR SUPPORT OF ANY KIND AND APPLE AND
-APPLE'S LICENSOR(S) (COLLECTIVELY REFERRED TO AS "APPLE" FOR THE
-PURPOSES OF SECTIONS 8 AND 9) AND ALL CONTRIBUTORS EXPRESSLY DISCLAIM
-ALL WARRANTIES AND/OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT
-NOT LIMITED TO, THE IMPLIED WARRANTIES AND/OR CONDITIONS OF
-MERCHANTABILITY, OF SATISFACTORY QUALITY, OF FITNESS FOR A PARTICULAR
-PURPOSE, OF ACCURACY, OF QUIET ENJOYMENT, AND NONINFRINGEMENT OF THIRD
-PARTY RIGHTS. APPLE AND EACH CONTRIBUTOR DOES NOT WARRANT AGAINST
-INTERFERENCE WITH YOUR ENJOYMENT OF THE COVERED CODE, THAT THE
-FUNCTIONS CONTAINED IN THE COVERED CODE WILL MEET YOUR REQUIREMENTS,
-THAT THE OPERATION OF THE COVERED CODE WILL BE UNINTERRUPTED OR
-ERROR-FREE, OR THAT DEFECTS IN THE COVERED CODE WILL BE CORRECTED. NO
-ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY APPLE, AN APPLE
-AUTHORIZED REPRESENTATIVE OR ANY CONTRIBUTOR SHALL CREATE A WARRANTY.
-You acknowledge that the Covered Code is not intended for use in the
-operation of nuclear facilities, aircraft navigation, communication
-systems, or air traffic control machines in which case the failure of
-the Covered Code could lead to death, personal injury, or severe
-physical or environmental damage.
-
-9. LIMITATION OF LIABILITY. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO
-EVENT SHALL APPLE OR ANY CONTRIBUTOR BE LIABLE FOR ANY INCIDENTAL,
-SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING
-TO THIS LICENSE OR YOUR USE OR INABILITY TO USE THE COVERED CODE, OR
-ANY PORTION THEREOF, WHETHER UNDER A THEORY OF CONTRACT, WARRANTY,
-TORT (INCLUDING NEGLIGENCE), PRODUCTS LIABILITY OR OTHERWISE, EVEN IF
-APPLE OR SUCH CONTRIBUTOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES AND NOTWITHSTANDING THE FAILURE OF ESSENTIAL PURPOSE OF ANY
-REMEDY. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF LIABILITY OF
-INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT APPLY
-TO YOU. In no event shall Apple's total liability to You for all
-damages (other than as may be required by applicable law) under this
-License exceed the amount of fifty dollars ($50.00).
-
-10. Trademarks. This License does not grant any rights to use the
-trademarks or trade names "Apple", "Apple Computer", "Mac", "Mac OS",
-"QuickTime", "QuickTime Streaming Server" or any other trademarks,
-service marks, logos or trade names belonging to Apple (collectively
-"Apple Marks") or to any trademark, service mark, logo or trade name
-belonging to any Contributor. You agree not to use any Apple Marks in
-or as part of the name of products derived from the Original Code or
-to endorse or promote products derived from the Original Code other
-than as expressly permitted by and in strict compliance at all times
-with Apple's third party trademark usage guidelines which are posted
-at http://www.apple.com/legal/guidelinesfor3rdparties.html.
-
-11. Ownership. Subject to the licenses granted under this License,
-each Contributor retains all rights, title and interest in and to any
-Modifications made by such Contributor. Apple retains all rights,
-title and interest in and to the Original Code and any Modifications
-made by or on behalf of Apple ("Apple Modifications"), and such Apple
-Modifications will not be automatically subject to this License. Apple
-may, at its sole discretion, choose to license such Apple
-Modifications under this License, or on different terms from those
-contained in this License or may choose not to license them at all.
-
-12. Termination.
-
-12.1 Termination. This License and the rights granted hereunder will
-terminate:
-
-(a) automatically without notice from Apple if You fail to comply with
-any term(s) of this License and fail to cure such breach within 30
-days of becoming aware of such breach;
-
-(b) immediately in the event of the circumstances described in Section
-13.5(b); or
-
-(c) automatically without notice from Apple if You, at any time during
-the term of this License, commence an action for patent infringement
-against Apple; provided that Apple did not first commence
-an action for patent infringement against You in that instance.
-
-12.2 Effect of Termination. Upon termination, You agree to immediately
-stop any further use, reproduction, modification, sublicensing and
-distribution of the Covered Code. All sublicenses to the Covered Code
-which have been properly granted prior to termination shall survive
-any termination of this License. Provisions which, by their nature,
-should remain in effect beyond the termination of this License shall
-survive, including but not limited to Sections 3, 5, 8, 9, 10, 11,
-12.2 and 13. No party will be liable to any other for compensation,
-indemnity or damages of any sort solely as a result of terminating
-this License in accordance with its terms, and termination of this
-License will be without prejudice to any other right or remedy of
-any party.
-
-13. Miscellaneous.
-
-13.1 Government End Users. The Covered Code is a "commercial item" as
-defined in FAR 2.101. Government software and technical data rights in
-the Covered Code include only those rights customarily provided to the
-public as defined in this License. This customary commercial license
-in technical data and software is provided in accordance with FAR
-12.211 (Technical Data) and 12.212 (Computer Software) and, for
-Department of Defense purchases, DFAR 252.227-7015 (Technical Data --
-Commercial Items) and 227.7202-3 (Rights in Commercial Computer
-Software or Computer Software Documentation). Accordingly, all U.S.
-Government End Users acquire Covered Code with only those rights set
-forth herein.
-
-13.2 Relationship of Parties. This License will not be construed as
-creating an agency, partnership, joint venture or any other form of
-legal association between or among You, Apple or any Contributor, and
-You will not represent to the contrary, whether expressly, by
-implication, appearance or otherwise.
-
-13.3 Independent Development. Nothing in this License will impair
-Apple's right to acquire, license, develop, have others develop for
-it, market and/or distribute technology or products that perform the
-same or similar functions as, or otherwise compete with,
-Modifications, Larger Works, technology or products that You may
-develop, produce, market or distribute.
-
-13.4 Waiver; Construction. Failure by Apple or any Contributor to
-enforce any provision of this License will not be deemed a waiver of
-future enforcement of that or any other provision. Any law or
-regulation which provides that the language of a contract shall be
-construed against the drafter will not apply to this License.
-
-13.5 Severability. (a) If for any reason a court of competent
-jurisdiction finds any provision of this License, or portion thereof,
-to be unenforceable, that provision of the License will be enforced to
-the maximum extent permissible so as to effect the economic benefits
-and intent of the parties, and the remainder of this License will
-continue in full force and effect. (b) Notwithstanding the foregoing,
-if applicable law prohibits or restricts You from fully and/or
-specifically complying with Sections 2 and/or 3 or prevents the
-enforceability of either of those Sections, this License will
-immediately terminate and You must immediately discontinue any use of
-the Covered Code and destroy all copies of it that are in your
-possession or control.
-
-13.6 Dispute Resolution. Any litigation or other dispute resolution
-between You and Apple relating to this License shall take place in the
-Northern District of California, and You and Apple hereby consent to
-the personal jurisdiction of, and venue in, the state and federal
-courts within that District with respect to this License. The
-application of the United Nations Convention on Contracts for the
-International Sale of Goods is expressly excluded.
-
-13.7 Entire Agreement; Governing Law. This License constitutes the
-entire agreement between the parties with respect to the subject
-matter hereof. This License shall be governed by the laws of the
-United States and the State of California, except that body of
-California law concerning conflicts of law.
-
-Where You are located in the province of Quebec, Canada, the following
-clause applies: The parties hereby confirm that they have requested
-that this License and all related documents be drafted in English. Les
-parties ont exige que le present contrat et tous les documents
-connexes soient rediges en anglais.

- Here is a matrix of mmap possibilities:
- mmap private not fixed
- mmap private fixed at somewhere currently unmapped
- mmap private fixed at somewhere already mapped
- mmap shared not fixed
- mmap shared fixed at somewhere currently unmapped
- mmap shared fixed at somewhere already mapped
- For private mappings, we should verify that changes cannot be read()
- back from the file, nor mmap's back from the file at a different
- address. (There have been systems where private was not correctly
- implemented like the infamous i386 svr4.0, and systems where the
- VM page cache was not coherent with the file system buffer cache
- like early versions of FreeBSD and possibly contemporary NetBSD.)
- For shared mappings, we should conversely verify that changes get
- propagated back to all the places they're supposed to be.
-
- Grep wants private fixed already mapped.
- The main things grep needs to know about mmap are:
- * does it exist and is it safe to write into the mmap'd area
- * how to use it (BSD variants) */

-.Sh NAME
-.Nm ConsoleMessage
-.\" The following lines are read in generating the apropos(man -k) database. Use only key
-.\" words here as the database is built based on the words here and in the .ND line.
-.\" Use .Nm macro to designate other names for the documented program.

-.Sh SYNOPSIS
-.Nm
-.Op Fl v
-.Ar message
-.Nm
-.Op Fl v
-.Fl S
-.Nm
-.Op Fl v
-.Fl F
-.Nm
-.Op Fl v
-.Fl s Ar service
-.Nm
-.Op Fl v
-.Fl f Ar service
-.Nm
-.Op Fl v
-.Fl q Ar setting
-.Nm
-.Op Fl v
-.Fl b Ar path
-.Nm
-.Op Fl v
-.Fl u
-.Sh DESCRIPTION
-The
-.Nm
-utility may be used by startup item scripts to send messages to
-.Nm SystemStarter
-(see SystemStarter(8)).
-.Pp
-The default behavior is to send the specified
-.Ar message
-to
-.Nm SystemStarter
-to be displayed on the console.
-.Nm SystemStarter
-will attempt to localize the string using the current startup item's localization dictionaries.
-.Pp
-.Nm
-may also be used to give feedback to
-.Nm SystemStarter
-indicating which services provided by the startup item have succeeded or failed.
-.Sh OPTIONS
-.Bl -tag -width -indent
-.It Fl v
-verbose mode (prints errors to stdout)
-.It Fl S
-mark all services provided by this item as successful
-.It Fl F
-mark all services provided by this item as failed
-.It Fl s
-mark the
-.Ar service
-as successful
-.It Fl f
-mark the
-.Ar service
-as failed
-.It Fl q
-query
-.Nm SystemStarter
-for the value of the configuration variable
-.Ar setting
-(result will be printed to stdout).
-.It Fl b
-Tell
-.Nm SystemStarter
-to load the display bundle at the specified
-.Ar path
-.It Fl u
-Tell
-.Nm SystemStarter
-to unload the current display bundle
-.El
-.Sh NOTES
-When a
-.Ar service
-name is not specified,
-.Nm
-assumes its parent process identification (see getppid(2)) is that of a startup item script, and uses that token to find the correct list of services provided by the current item. If the process calling
-.Nm
-is not a startup item script, it is necessary to explicitly provide
-.Ar service
-names.
-.Sh SEE ALSO
-.\" List links in ascending order by section, alphabetically within a section.
-.\" Please do not reference files that do not exist without filing a bug report
-.Xr SystemStarter 8
-.\" .Sh BUGS \" Document known, unremedied bugs

subsystem bootstrap 400;
-/*
- * Interface: Bootstrap server
- *
- * The bootstrap server is the first user-mode task initiated by the Mach
- * kernel at system boot time. The bootstrap server provides two services,
- * it initiates other system tasks, and manages a table of name-port bindings
- * for fundamental system services (e.g. lookupd, Window Manager, etc...).
- *
- * Name-port bindings can be established with the bootstrap server by either
- * of two mechanisms:
- *
- * 1. The binding can be indicated, in advance of the service that backs it
- * being available, via a "service create" request. In this case, bootstrap
- * will immediately create a port and bind the indicated name with that port.
- * At a later time, a service may "checkin" for the name-port
- * binding and will be returned receive rights for the bound port. Lookup's
- * on bindings created by this mechanism will return send rights to the port,
- * even if no service has "checked-in". In this case, requests sent to the
- * bound port will be queued until a server has checked-in and can satisfy the
- * request.
- *
- * 2. Bindings can be established dynamically via a "register" request. In
- * this case, the register request provides bootstrap with a name and send
- * rights for a port. Bootstrap will provide send rights for the bound port
- * to any requestor via the lookup request.
- *
- * Bootstrap provides its service port to descendant tasks via the Mach
- * "bootstrap" special task port. All direct descendants of bootstrap receive
- * a "privileged" bootstrap service port. System services that initiate
- * untrusted tasks should replace the Mach bootstrap task special port with
- * a subset bootstrap port to prevent them from infecting the namespace.
- *
- * The bootstrap server creates a "backup" port for each service that it
- * creates. This is used to detect when a checked out service is no longer
- * being served. The bootstrap server regains all rights to the port and
- * it is marked available for check-out again. This allows crashed servers to
- * resume service to previous clients. Lookup's on this named port will
- * continue to be serviced by bootstrap while holding receive rights for the
- * bound port. A client may detect that the service is inactive via the
- * bootstrap status request. If an inactive service re-registers rather
- * than "checking-in" the original bound port is destroyed.
- *
- * The status of a named service may be obtained via the "status" request.
- * A service is "active" if a name-port binding exists and receive rights
- * to the bound port are held by a task other than bootstrap.
- *
- * The bootstrap server may also (re)start server processes associated with
- * with a set of services. The definition of the server process is done
- * through the "create server" request. The server will be launched in the
- * same bootstrap context in which it was registered.

+
+/*
+ * Interface: Bootstrap server
+ *
+ * The bootstrap server is the first user-mode task initiated by the Mach
+ * kernel at system boot time. The bootstrap server provides two services,
+ * it initiates other system tasks, and manages a table of name-port bindings
+ * for fundamental system services (e.g. lookupd, Window Manager, etc...).
+ *
+ * Name-port bindings can be established with the bootstrap server by either
+ * of two mechanisms:
+ *
+ * 1. The binding can be indicated, in advance of the service that backs it
+ * being available, via a "service create" request. In this case, bootstrap
+ * will immediately create a port and bind the indicated name with that port.
+ * At a later time, a service may "checkin" for the name-port
+ * binding and will be returned receive rights for the bound port. Lookup's
+ * on bindings created by this mechanism will return send rights to the port,
+ * even if no service has "checked-in". In this case, requests sent to the
+ * bound port will be queued until a server has checked-in and can satisfy the
+ * request.
+ *
+ * 2. Bindings can be established dynamically via a "register" request. In
+ * this case, the register request provides bootstrap with a name and send
+ * rights for a port. Bootstrap will provide send rights for the bound port
+ * to any requestor via the lookup request.
+ *
+ * Bootstrap provides its service port to descendant tasks via the Mach
+ * "bootstrap" special task port. All direct descendants of bootstrap receive
+ * a "privileged" bootstrap service port. System services that initiate
+ * untrusted tasks should replace the Mach bootstrap task special port with
+ * a subset bootstrap port to prevent them from infecting the namespace.
+ *
+ * The bootstrap server creates a "backup" port for each service that it
+ * creates. This is used to detect when a checked out service is no longer
+ * being served. The bootstrap server regains all rights to the port and
+ * it is marked available for check-out again. This allows crashed servers to
+ * resume service to previous clients. Lookup's on this named port will
+ * continue to be serviced by bootstrap while holding receive rights for the
+ * bound port. A client may detect that the service is inactive via the
+ * bootstrap status request. If an inactive service re-registers rather
+ * than "checking-in" the original bound port is destroyed.
+ *
+ * The status of a named service may be obtained via the "status" request.
+ * A service is "active" if a name-port binding exists and receive rights
+ * to the bound port are held by a task other than bootstrap.
+ *
+ * The bootstrap server may also (re)start server processes associated with
+ * with a set of services. The definition of the server process is done
+ * through the "create server" request. The server will be launched in the
+ * same bootstrap context in which it was registered.

-.Os BSD 4
-.Sh NAME
-.Nm init
-.Nd process control initialization
-.Sh SYNOPSIS
-.Nm init
-.Sh DESCRIPTION
-The
-.Nm init
-program
-is the last stage of the boot process.
-It normally runs the automatic reboot sequence as described in
-.Xr reboot 8 ,
-and if this succeeds, begins multi-user operation.
-If the reboot scripts fail,
-.Nm init
-commences single user operation by giving
-the super-user a shell on the console.
-The
-.Nm init
-program may be passed parameters
-from the boot program to
-prevent the system from going multi-user and to instead execute
-a single user shell without starting the normal daemons.
-The system is then quiescent for maintenance work and may
-later be made to go to multi-user by exiting the
-single-user shell (with ^D).
-This
-causes
-.Nm init
-to run the
-.Pa /etc/rc
-start up command file in fastboot mode (skipping disk checks).
-.Pp
-If the
-.Nm console
-entry in the
-.Xr ttys 5
-file is marked ``insecure'',
-then
-.Nm init
-will require that the superuser password be
-entered before the system will start a single-user shell.
-The password check is skipped if the
-.Nm console
-is marked as ``secure''.
-.Pp
-The kernel runs with four different levels of security.
-Any superuser process can raise the security level, but only
-.Nm init
-can lower it.
-Security levels are defined as follows:
-.Bl -tag -width flag
-.It Ic -1
-Permanently insecure mode \- always run system in level 0 mode.
-.It Ic 0
-Insecure mode \- immutable and append-only flags may be turned off.
-All devices may be read or written subject to their permissions.
-.It Ic 1
-Secure mode \- immutable and append-only flags may not be changed;
-disks for mounted filesystems,
-.Pa /dev/mem ,
-and
-.Pa /dev/kmem
-are read-only.
-The
-.Xr settimeofday 2
-system call can only advance the time.
-.It Ic 2
-Highly secure mode \- same as secure mode, plus disks are always
-read-only whether mounted or not.
-This level precludes tampering with filesystems by unmounting them,
-but also inhibits running
-.Xr newfs 8
-while the system is multi-user.
-.El
-.Pp
-Normally, the system runs in level 0 mode while single user
-and in level 1 mode while multiuser.
-If the level 2 mode is desired while running multiuser,
-it can be set in the startup script
-.Pa /etc/rc
-using
-.Xr sysctl 8 .
-If it is desired to run the system in level 0 mode while multiuser,
-the administrator must build a kernel with the variable
-.Nm securelevel
-defined in the file
-.Pa /sys/compile/MACHINE/param.c
-and initialize it to -1.
-.Pp
-In multi-user operation,
-.Nm init
-maintains
-processes for the terminal ports found in the file
-.Xr ttys 5 .
-.Nm Init
-reads this file, and executes the command found in the second field.
-This command is usually
-.Xr getty 8 ;
-.Xr getty
-opens and initializes the tty line
-and
-executes the
-.Xr login
-program.
-The
-.Xr login
-program, when a valid user logs in,
-executes a shell for that user. When this shell
-dies, either because the user logged out
-or an abnormal termination occurred (a signal),
-the
-.Nm init
-program wakes up, deletes the user
-from the
-.Xr utmp 5
-file of current users and records the logout in the
-.Xr wtmp
-file.
-The cycle is
-then restarted by
-.Nm init
-executing a new
-.Xr getty
-for the line.
-.pl +1
-.Pp
-Line status (on, off, secure, getty, or window information)
-may be changed in the
-.Xr ttys
-file without a reboot by sending the signal
-.Dv SIGHUP
-to
-.Nm init
-with the command
-.Dq Li "kill \-s HUP 1" .
-On receipt of this signal,
-.Nm init
-re-reads the
-.Xr ttys
-file.
-When a line is turned off in
-.Xr ttys ,
-.Nm init
-will send a SIGHUP signal to the controlling process
-for the session associated with the line.
-For any lines that were previously turned off in the
-.Xr ttys
-file and are now on,
-.Nm init
-executes a new
-.Xr getty
-to enable a new login.
-If the getty or window field for a line is changed,
-the change takes effect at the end of the current
-login session (e.g., the next time
-.Nm init
-starts a process on the line).
-If a line is commented out or deleted from
-.Xr ttys ,
-.Nm init
-will not do anything at all to that line.
-However, it will complain that the relationship between lines
-in the
-.Xr ttys
-file and records in the
-.Xr utmp
-file is out of sync,
-so this practice is not recommended.
-.Pp
-.Nm Init
-will terminate multi-user operations and resume single-user mode
-if sent a terminate
-.Pq Dv TERM
-signal, for example,
-.Dq Li "kill \-s TERM 1" .
-If there are processes outstanding that are deadlocked (because of
-hardware or software failure),
-.Xr init
-will not wait for them all to die (which might take forever), but
-will time out after 30 seconds and print a warning message.
-.Pp
-.Nm Init
-will cease creating new
-.Xr getty Ns 's
-and allow the system to slowly die away, if it is sent a terminal stop
-.Pq Dv TSTP
-signal, i.e.
-.Dq Li "kill \-s TSTP 1" .
-A later hangup will resume full
-multi-user operations, or a terminate will start a single user shell.
-This hook is used by
-.Xr reboot 8
-and

-.Pp
-The role of
-.Nm init
-is so critical that if it dies, the system will reboot itself
-automatically.
-If, at bootstrap time, the
-.Xr init
-process cannot be located, the system will panic with the message
-``panic: "init died (signal %d, exit %d)''.
-.Sh DIAGNOSTICS
-.Bl -diag
-.It "getty repeating too quickly on port %s, sleeping"
-A process being started to service a line is exiting quickly
-each time it is started.
-This is often caused by a ringing or noisy terminal line.
-.Em "Init will sleep for 10 seconds" ,
-.Em "then continue trying to start the process" .
-.Pp
-.It "some processes would not die; ps axl advised."
-A process
-is hung and could not be killed when the system was shutting down.
-This condition is usually caused by a process
-that is stuck in a device driver because of
-a persistent device error condition.

.Sh SUBCOMMANDS
.Bl -tag -width -indent
.It Xo Ar load Op Fl wF
+.Op Fl S Ar sessiontype
+.Op Fl D Ar domain
.Ar paths ...
.Xc
Load the specified configuration files or directories of configuration files.
+Jobs that are not on-demand will be started as soon as possible.
+All specified jobs will be loaded before any of them are allowed to start.
.Bl -tag -width -indent
.It Fl w
Remove the disabled key and write the configuration files back out to disk.
.It Fl F
Force the loading of the plist. Ignore the Disabled key.
+.It Fl S Ar sessiontype
+Some jobs only make sense in certain contexts. This flag instructs
+.Nm launchctl
+to look for jobs in a different location when using the -D flag, and allows
+.Nm launchctl
+to restrict which jobs are loaded into which session types. Currently known
+session types include: Aqua, X11 and tty.
+.It Fl D Ar domain
+Look for
+.Xr plist 5 files ending in *.plist in the domain given. Valid domains include
+"system," "local," "network" and "all." When providing a session type, an additional
+domain is available for use called "user." For example, without a session type given,
+"-D system" would load from property list files from /System/Library/LaunchDaemons.
+With a session type passed, it would load from /System/Library/LaunchAgents.
.El
.It Xo Ar unload Op Fl w
.Ar paths ...
.Xc
Unload the specified configuration files or directories of configuration files.
+This will also stop the job if it is running.
.Bl -tag -width -indent
.It Fl w
Add the disabled key and write the configuration files back out to disk.
.El
-.It Ar start Ar joblabels ...
-Start the specified jobs by label.
-.It Ar stop Ar joblabels ...
-Stop the specified jobs by label. Jobs may restart automatically if demand driven.
+.It Xo Ar submit Fl l Ar label
+.Op Fl p Ar executable
+.Op Fl o Ar path
+.Op Fl e Ar path
+.Ar -- command
+.Op Ar args
+.Xc
+A simple way of submitting a program to run without a configuration file. This mechanism also tells launchd to keep the program alive in the event of failure.
+.Bl -tag -width -indent
+.It Fl l Ar label
+What unique label to assign this job to launchd.
+.It Fl p Ar program
+What program to really execute, regardless of what follows the -- in the submit sub-command.
+.It Fl o Ar path
+Where to send the stdout of the program.
+.It Fl e Ar path
+Where to send the stderr of the program.
+.El
+.It Ar remove Ar job_label
+Remove the jobs from launchd by label.
+.It Ar start Ar job_label
+Start the specified jobs by label. The expected use of this subcommand is for
+debugging and testing so that one can manually kick-start an on-demand server.
+.It Ar stop Ar job_label
+Stop the specified jobs by label. If a job is on-demand, launchd may immediately
+restart the job if launchd finds any criteria that is satisfied.
+Non-demand based jobs will always be restarted. Use of this subcommand is discouraged.
+Jobs should ideally idle timeout by themselves.
.It Ar list
List all of the jobs loaded into
.Nm launchd .
.Xr umask 2
of
.Nm launchd .
+.It Ar bslist Op Ar PID
+This prints out Mach bootstrap services and their respective states. While the
+namespace appears flat, it is in fact hierarchical, thus allowing for certain
+services to be only available to a subset of processes. The three states a
+service can be in are active ("A"), in-active ("I") and on-demand ("D").
+.It Ar bsexec Ar PID command Op Ar args
+This executes the given command in the same Mach bootstrap namespace hierachy
+as the given PID.
.It Ar help
Print out a quick usage statement.

.Op Ar -- command Op Ar args ...
.Sh DESCRIPTION
.Nm
-manages daemons, both for the system as a whole and for individual users. Ideal daemons can launch
-on demand based on criteria specified in their respective XML property lists located in one of the
-directories specified in the FILES section.
+manages processes, both for the system as a whole and for individual users.
+The primary and preferred interface to
+.Nm
+is via the
+.Xr launchctl 1
+tool which (among other options) allows the user or administrator to load and unload jobs.
+Where possible, it is preferable for jobs to launch on demand based on criteria specified
+in their respective configuration files.
.Pp
When run with a command, a specific instance of
.Nm
During boot
.Nm
is invoked by the kernel to run as the first process on the system and to further bootstrap the rest of the system.
-.Sh OPTIONS WHEN RUN AS PID 1
+.Sh OPTIONS
.Bl -tag -width -indent
.It Fl d
Daemonize. Useful when passing a command to launchd on the command line.
-.It Fl v
-Verbose boot.
+.It Fl D
+Debug. Prints syslog messages to stderr and adjusts logging via
+.Xr syslog 3
+to LOG_DEBUG.
+.It Fl S Ar SessionType
+Instruct launchd to which session type it is.

.It Sy Label <string>
.It Sy Disabled <boolean>
This optional key is used to disable your job. The default is false.
.It Sy UserName <string>
-This optional key specifies the user to run the job as. The default is the user who submitted the job to
-.Nm launchd .
+This optional key specifies the user to run the job as. This key is only applicable when launchd is running as root.

+This configuration file only applies to sessions of the type specified. This key is used
+in concert with the -S flag to
+.Nm launchctl .
.It Sy ProgramArguments <array of strings>
This required key maps to the second argument of
.Xr execvp 3 .
This optional key maps to the first argument of
.Xr execvp 3 .
If this key is missing, then the first element of the array of strings provided to the ProgramArguments will be used instead.
+.It Sy EnableGlobbing <boolean>
+This flag causes
+.Nm launchd
+to use the
+.Xr glob 3
+mechanism to update the program arguments before invocation.
.It Sy OnDemand <boolean>
-This optional key is used to control whether your job is launched based on demand or to be kept continuously running. The default is true.
+This key was used in Mac OS X 10.4 to control whether a job was kept alive or not. The default was true.
+This key has been deprecated and replaced in Mac OS X 10.5 with the more powerful KeepAlive option.
+.It Sy KeepAlive <boolean or dictionary of stuff>
+This optional key is used to control whether your job is to be kept
+continuously running or to let demand and conditions control the invocation. The
+default is false and therefore only demand will start the job. The value may be
+set to true to unconditionally keep the job alive. Alternatively, a dictionary
+of conditions may be specified to selectively control whether
+.Nm launchd
+keeps a job alive or not. If multiple keys are provided, launchd ORs them, thus
+providing maximum flexibility to the job to refine the logic and stall if necessary. If
+.Nm launchd
+finds no reason to restart the job, it falls back on demand based invocation.
+Jobs that exit quickly and frequently when configured to be kept alive will be
+throttled to converve system resources.
+.Bl -ohang -offset indent
+.It Sy SuccessfulExit <boolean>
+If true, the job will be restarted as long as the program exits and with an exit
+status of zero. If false, the job will be restarted in the inverse condition.
+This key implies that "RunAtLoad" is set to true, since the job needs to run at
+least once before we can get an exit status.
+.It Sy NetworkState <boolean>
+If true, the job will be kept alive as long as the network is up, where up is
+defined as at least one non-loopback interface being up and having IPv4 or IPv6
+addresses assigned to them.
+If false, the job will be kept alive in the inverse condition.
+.It Sy PathState <dictionary of booleans>
+Each key in this dictionary is a file-system path. If the value of the key is
+true, then the job will be kept alive as long as the path exists.
+If false, the job will be kept alive in the inverse condition. The intent of this
+feature is that two or more jobs may create semaphores in the file-system namespace.

+The recommended time out (in seconds) to pass to the job. If no value is specified, a default time out will be supplied by

.It Sy InitGroups <boolean>
If the system is asleep, the job will be started the next time the computer
wakes up. If multiple intervals transpire before the computer is woken, those
events will be coalesced into one event upon wake from sleep.
-.It Sy StartCalendarInterval <dictionary of integers>
+.It Sy StartCalendarInterval <dictionary of integers or array of dictionary of integers>
This optional key causes the job to be started every calendar interval as specified. Missing arguments are considered to be wildcard. The semantics are much like
.Xr crontab 5 .
Unlike cron which skips job invocations when the computer is asleep, launchd
This optional key specifies that
.Nm launchd
should adjust its log mask temporarily to LOG_DEBUG while dealing with this job.
+.It Sy WaitForDebugger <boolean>
+This optional key specifies that
+.Nm launchd
+should instruct the kernel to have the job wait for a debugger to attach before any code in the job is executed.
.It Sy SoftResourceLimits <dictionary of integers>
.It Sy HardResourceLimits <dictionary of integers>
Resource limits to be imposed on the job. These adjust variables set with
value should be applied to the daemon.
.It Sy LowPriorityIO <boolean>
This optional key specifies whether the kernel should consider this daemon to be low priority when doing file system I/O.
+.It Sy MachServices <dictionary of booleans>
+This optional key is used to specify Mach services to be registered with the
+Mach bootstrap sub-system. Each key in this dictionary should be the name of
+service to be advertised. The value of the key must be a boolean. If the
+boolean is true, the port is recycled, thus leaving clients to remain oblivious
+to the demand nature of job. If the value is set to false, clients receive port
+death notifications when the job lets go of the receive right. The port will be
+recreated atomically with respect to bootstrap_look_up() calls, so that clients
+can trust that after receiving a port death notification, the new port will
+have already been recreated. Setting the value to false should be done with
+care. Not all clients may be able to handle this behavior. Finally, for the job
+itself, the values will be replaced with Mach ports at the time of check-in
+with
+.Nm launchd .
.It Sy Sockets <dictionary of dictionaries... OR dictionary of array of dictionaries...>

.Nm launchd

.Xr bind 2

+.It Sy SecureSocketWithKey <string>
+This optional key is a variant of SockPathName. Instead of binding to a known
+path, a securely generated socket is created and the path is assigned to the
+environment variable that is inherited by all jobs spawned by launchd.
.It Sy SockPathMode <integer>
-This optional key specifies the mode of the socket. Known bug: Property lists don't support octal, so please convert the value to decimal.
+This optional key specifies the mode of the socket. Known bug: Property lists
+don't support octal, so please convert the value to decimal.
.It Sy Bonjour <boolean or string or array of strings>
This optional key can be used to request that the service be registered with the
.Xr mDNSResponder 8 .
If the value is a hostname, then
.Xr getaddrinfo 3
will be used to join the correct multicast address for a given socket family.
-If an explicit IPv4 or IPv6 address is given, it is required that the SockFamily family also be set, otherwise the results are undefined.

+.Sh DEPENDENCIES
+Unlike many bootstrapping daemons, launchd has no explicit dependency model.
+Interdependencies are expected to be solved through the use of IPC.
+It is therefore in the best interest of a job developer who expects dependents
+to define all of the sockets in the configuration file. This has the added
+benefit of making it possible to start the job based on demand instead of
+immediately.

.Sh NAME
.Nm rc
-.Nd command script for auto\-reboot and daemons
+.Nd command script for boot
.Sh SYNOPSIS
.Nm rc
.Nm rc.local
.Sh DESCRIPTION
-.Nm Rc
-is the command script which controls the automatic reboot and
-.Nm rc.local
-is the script holding commands which are pertinent only
-to a specific site.
-.Pp
-When an automatic reboot is in progress,
-.Nm rc
-is invoked with the argument
-.Em autoboot .
-The first portion of
+Prior to Mac OS X 10.5, the
.Nm rc
-runs an
-.Xr fsck 8
-with option
-.Fl p
-to ``preen'' all the disks of minor inconsistencies resulting
-from the last system shutdown and to check for serious inconsistencies
-caused by hardware or software failure.
-If this auto-check and repair succeeds, then the second part of
-.Nm rc
-is run.
-.Pp
-The second part of
-.Nm rc ,
-which is run after an auto-reboot succeeds and also if
-.Nm rc
-is invoked when a single user shell terminates (see
-.Xr init 8 ) ,
-starts all the daemons on the system, preserves editor files
-and clears the scratch directory
-.Pa /tmp .
-.Pp
-.Nm Rc.local
-is executed immediately before any other commands after a successful
-.Xr fsck .
-Normally, the first commands placed in the
+script
+was used to bootstrap the OS. As of Leopard, the system is self-bootstrapped via
+.Xr launchd 8
+which uses the
+.Xr launchctl 1
+bootstrap subcommand to read in launchd jobs from the standard locations.
+For compatibility reasons, the
.Nm rc.local
-file define the machine's name, using
-.Xr hostname 1 ,
-and save any possible core image that might have been
-generated as a result of a system crash, with
-.Xr savecore 8 .
-The latter command is included in the
-.Nm rc.local
-file because the directory in which core dumps are saved
-is usually site specific.
+script still continues to work.
.Pp
-Following tradition, the startup files
-.Nm rc
-and
+The startup file
.Nm rc.local
reside in
.Pa /etc .
.Sh SEE ALSO
-.Xr init 8 ,
-.Xr reboot 8 ,
-.Xr savecore 8
-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Bx 4.0 .
